    Abstract: Disclosed is an aluminum electrolytic cell having profiled cathode carbon blocks structures, comprising a cell case, a refractory material installed on the bottom, an anodes and a cathode. The cathode carbon blocks include a profiled structure having projections on the top surface of the carbon blocks, that is, a plurality of projections are formed on a surface of the cathode carbon blocks. The aluminum electrolytic cell having the cathode structure according to the present invention can reduce the velocity of the flow and the fluctuation of the level of the cathodal molten aluminum within the electrolytic cell, so as to increase the stability of the surface of molten aluminum, reduce the molten lose of the aluminum, increase the current efficiency, reduce the inter electrode distance, and reduce the energy consumption of the production of aluminum by electrolysis. With the above configuration, compounds or precipitates of viscous cryolite molten alumina can be formed on the lower portion between walls protruding on the upper surface of the cathode, which can prohibit the molten aluminum from flowing into the cell bottom through the cracks and apertures on cathodes, so that the life of the electrolytic cell can be extended.

    Abstract: Embodiments identify joints of a multi-limb body in an image. One such embodiment unifies depth of a plurality of multi-scale feature maps generated from an image of a multi-limb body to create a plurality of feature maps each having a same depth. In turn, for each of the plurality of feature maps having the same depth, an initial indication of one or more joints in the image is generated. The one or more joints are located at an interconnection of a limb to the multi-limb body or at an interconnection of a limb to another limb. To continue, a final indication of the one or more joints in the image is generated using each generated initial indication of the one or more joints.

    Abstract: The invention relates to a large-scale three-dimensional physical simulation test system for the whole development process of deep engineering rock burst. A CO2 blast cracking device, a dynamic fiber grating and ultrasonic probes are pre-embedded in a physical model sample of similar materials. Acoustic emission probes are pre-mounted on the boundary of a sample. A tunnel excavated in the sample is provided with a three-way acceleration sensor and an industrial endoscope. A sample 3D printer and a drop hammer impact device are arranged outside the three-dimensional static stress loading device. A hydraulic oil source and a controller are arranged outside the three-dimensional static stress loading device and mounted on the ground. The controller is connected with a computer.
